Synthesis and the crystal and molecular structure of the Sn(IV)–Nd(III) coordination polymer based on the tartaric acid [NdSn2{H(Tart)3} · 12H2O]n

Аннотация

The polymeric heterometallic [NdSn₂{H(Tart)₃} ∙ 12H₂O]_n (I) compound, where H₄Tart is the tartaric acid, is synthesized and characterized by elemental analysis, X-ray diffraction, thermogravimetry, and IR spectroscopy. The structural elements of crystal I, namely, polymeric [{Nd(H₂O)₆}(μ₃-H_nTart^4–n) {Sn(μ₂-H_nTart^4–n)}₂} (n = 0, 1) complex molecules and crystallization water molecules, are connected by an extended hydrogen-bond system.
